Grakliani Hill is an archaeological excavation site in eastern Georgia near Kaspi, showing evidence of human presence possibly going back 300,000 years.
The site was discovered in 2007, during work to widen the Tbilisi-Senaki-Leselidze highway. Research is being done by students and faculty from Tbilisi State University. In 2015, a script was discovered on the altar of a fertility goddess's temple, predating those previously known in the area by at least a thousand years.
The site contains a temple to a fertility goddess from the seventh century BCE, a pit-type burial cemetery from the early Bronze Age, and the remains of a building from around 450-350 BCE; the building consists of three rooms with three storage rooms.
The site had been occupied between the Chalcolithic and the Late Hellenistic periods.
The excavation of layers yielded artifacts including children's toys, weapons, icons, and pharmacological devices. Within the first two months of digging, archaeologists had excavated over 35,000 pieces from hundreds of graves and ruins of settlements that date back to the eighth century BCE.
Several golden and bronze discs from the sixth century were discovered. These findings attest that this society possessed the technology of gilding and engraving.
Among the most significant artifacts may be a fourth century BCE printing device. These were extremely rare seals used to stamp judicial documents; supposedly they originated from Uruk in Mesopotamia. Another notable find is that of a large and decorated ritual oven, an unprecedented find in archaeology.
A previously unknown script was discovered just below a temple's collapsed altar to a fertility goddess from the seventh century BCE. These inscriptions differ from those at other temples at Grakliani, which show animals, people, or decorative elements. The script bears no resemblance to any alphabet currently known, although its letters are conjectured to be related to ancient Greek and Aramaic. The inscription appears to be the oldest native alphabet to be discovered in the whole Caucasus region, a thousand years older than any indigenous writing previously discovered in the region. In comparison, the earliest Armenian and Georgian scripts date from the fifth century AD, just after the respective cultures converted to Christianity. By September 2015, an area of 31 by 3 inches of the inscription had been excavated.
